Question:
The zero point keeps drifting on my unit. I have leveled my 5th wheel using a bubble level. I set zero then come back next day and level is off. Seems to be only front left right and front back. Back left right stays zero. Is my main control board bad? Any diagnostic I can run?

Hey Jeff,
There are a few things that could be causing your zero point to drift. Its possible there is some fluid loss in the hydraulic system, a possible leak in the hydraulic lines. It could also be a bad control board or controller. There are steps you can run to re-calibrate the zero point on your system which could fix the issue. I will list those steps out for you below.
Zero Point Calibration
The “Zero Point” is the programmed point that the trailer will return
to each time the Auto Level feature is used.
Note: Prior to starting this procedure, double check all connections
on the controller, jacks, and touch pad.
1. In manual mode, run the jacks to level the trailer. This is best
achieved by placing a level in the center of the trailer and leveling
it both front to back and then side to side. (See “Basic Jack
Operation” for instructions on how to manually operate the system).
2. Once the trailer is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button five (5) times and then press and release the “REAR” button five (5) times.
4. The touch pad will flash and beep and the display will read “ZERO
POINT CALIBRATION ENTER to set, Power to Exit”.
5. To set the current position as the zero point, press the “ENTER”
button.
6. LCD display will read “Zero point stability check”.
7. LCD display will read “Zero point set successfully” once process is
complete.
8. The system will set this point as its level state and the touch pad
will turn off.
If you are still having issues after this let me know and I can keep troubleshooting.
